Most helpful review for Garrett Sea Hunter Mark II

Great machine... Know what you are doing
To call this machine rubbish or junk is just ignorant. I've used PI machines for years in many places and I know them well, so I will try and help some people out with this review.

The SHM11 is a machine for diggers. Period. If you don't like to dig nails, or bottle caps, or fish hooks, sinkers, etc... Don't get this machine, but you will miss the pleasant surprises that come from hearing a very faint, sometimes almost imperceptible tone, taking a scoop, getting louder, another scoop, blowing your ears out , and BAM! A nice gold ring in the scoop that the VLF guys went right over.

There is a phenomenon with PI detectors that causes them to detect objects deeper in salt water and wet salt sand than in air alone, so air tests are not accurate. Because it is a PI machine, iron reads as a good conductor, so there is NO WAY you can discriminate iron, and any amount of an attempt at discrimination will cost you depth.
This is what you have to do... Run on zero discrimination on standard mode and forget discreet mode, It costs you depth. There will be a natural wavering of the tone, and in highly mineralized sand you will get a false signal if you touch the coil to the sand, but you will get a slight, or loud, sharp, REPEATABLE increase in volume when you go over a target.

No matter what Garrett tells you, or anyone tells you, you can NOT eliminate an aluminum pop top and still pick up a gold ring. It is the science of metal, not my opinion.
Gold is lower in conductivity than aluminum and the size an karat amount will determine how hard it is to detect. Gold is a POOR conductor. It is used in electronics for it's high corrosion resistance, not conductivity. You may get lucky and pick up large, thick men's rings with disc. set higher, but you will miss a lot.

If you live on the Texas Gulf coast where there are lots of nails and junk in the water, you either dig until you are sore, or try a VLF detector that will discriminate iron. High trash areas will be frustrating and discouraging.

Here is a good way to find out if you will find gold rings... No nickels dug, No pull tabs dug = No gold rings dug. It is that simple. As far as quality of the machine... It is built like a tank. Very durable and leak proof.

The volume is loud because it is a DIVING detector. Divers need the loud volume to hear targets over their bubbles. As far as Garrett goes, I don't think anyone can dispute that their customer service is the best in the business. If you have a problem, just call them and they will make it right by you, without fail.

Brand bashing is irresponsible and I have tried a lot of the leading brands. They all have pros and cons, features that I liked, and some I disliked. No machine is perfect for all applications. It is unreasonable to think anyone can build a machine that is, because it is impossible. Detecting successfully is a science, you don't learn it all in a week, a year, or ever. It is a never-ending learning process.

If you do decide on the Sea Hunter... Read some books, turn your disc. down to zero, be persistent, learn your machine, slow down and enjoy being outside and getting some exercise. You will be rewarded over time...

I hope I helped some of you with facts I learned the hard way and from men who knew a lot more than I.

Surf Master PI Pro
Call it bang for the buck. I've used this PI PRO two full seasons and I can't be more pleased. It goes deep doesn't everyone say that. I often scoop holes so deep that during the recovery I have to bounce on the scoop to get it to bite then step out and to the side of the hole and pull the scoop out. I'd be over my head otherwise.

I've recovered very small thin rings that were approx 1/2 dwt. a small white gold floating heart that was almost 2/3 dwt. The larger gold and platinum wasn't able to hide as well.

I use a Fisher shaft weight as I have the lighter coil, works well, minimum effort to keep it on the bottom. If you are going to hunt mostly in the water like me you should consider the weighted coil. Otherwise just get the shaft weight and light coil, if you like to hunt the wet sand too.

The PI PRO is not my first choice for dry sand (the big ashtray) as there is usually so much trash & foil I grab a VLF. But dry sand is a night hunt thing for me, while the sharks are feeding.
Battery life is fine, I keep track of my time and change them when I get to about 20 hours to avoid having to do it when I'm hunting and the PI is wet. You also should break down and clean the rods after each salt water hunt so they don't freeze.
One nice feature is being able to use the edge of the coil to pinpiont or detect crevices in the rocks.
You'll hear the SAT doing it's thing as you lower the coil beneath the surface then get it to the bottom where it gets smooth and does not false. It will pick up red bricks though and every piece of junk around. Hey, I've pulled gold, silver and old coins out of the ocean that were under iron.

I can buy any detector Aquastar, Excal etc. but the PI PRO performance price break is unbeatable IMHO. So with the cash saved over the other choices I bought a new CZ-20 too. So goes life with a PI PRO...dig it all leave the place cleaner than you found it. You can see some PI finds of mine at Whites web site under customer stories.
